It runs perfectly fine on a Wandboard quad. MFC r271204 with manual intervention: Fix the handling of sysctl variables when used with VIMAGE. While there do some cleanup of the code. MFC r271209: Fix a leak of an address, if the address is scheduled for removal and the stack is torn down. Thanks to Peter Bostroem and Jiayang Liu from Google for reporting the issue. MFC r271219: Use SYSCTL_PROC instead of SYSCTL_VNET_PROC. Suggested by: glebius@ MFC r271221: Use union sctp_sockstore instead of struct sockaddr_storage. This eliminates some warnings when building in userland. Thanks to Patrick Laimbock for reporting this issue. Remove also some unnecessary casts. There should be no functional change. MFC r271228: Address another warnings reported by Patrick Laimbock when compiling in userspace. While there, improve consistency. MFC r271230: Address warnings generated by the clang analyzer.

| | | | | | | | | | | | | | | | | Use an RLOCK here instead of an RWLOCK - matching all the other calls to lla_lookup(). This drastically reduces the very high lock contention when doing parallel TCP throughput tests (> 1024 sockets) with IPv6. MFC r260187: lla_lookup() does modification only when LLE_CREATE is specified. Thus we can use IF_AFDATA_RLOCK() instead of IF_AFDATA_LOCK() when doing lla_lookup() without LLE_CREATE flag. MFC r260217: Add IF_AFDATA_WLOCK_ASSERT() in case lla_lookup() is called with LLE_CREATE flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | features. The changes in particular are: o Remove rarely used "header" pointer and replace it with a 64bit protocol/ layer specific union PH_loc for local use. Protocols can flexibly overlay their own 8 to 64 bit fields to store information while the packet is worked on. o Mechanically convert IP reassembly, IGMP/MLD and ATM to use pkthdr.PH_loc instead of pkthdr.header. o Extend csum_flags to 64bits to allow for additional future offload information to be carried (e.g. iSCSI, IPsec offload, and others). o Move the RSS hash type enumerator from abusing m_flags to its own 8bit rsstype field. Adjust accessor macros. o Add cosqos field to store Class of Service / Quality of Service information with the packet. It is not yet supported in any drivers but allows us to get on par with Cisco/Juniper in routing applications (plus MPLS QoS) with a modernized ALTQ. o Add four 8 bit fields l[2-5]hlen to store the relative header offsets from the start of the packet. This is important for various offload capabilities and to relieve the drivers from having to parse the packet and protocol headers to find out location of checksums and other information. Header parsing in drivers is a lot of copy-paste and unhandled corner cases which we want to avoid. o Add another flexible 64bit union to map various additional persistent packet information, like ether_vtag, tso_segsz and csum fields. Depending on the csum_flags settings some fields may have different usage making it very flexible and adaptable to future capabilities. o Restructure the CSUM flags to better signify their outbound (down the stack) and inbound (up the stack) use. The CSUM flags used to be a bit chaotic and rather poorly documented leading to incorrect use in many places. Bring clarity into their use through better naming. Compatibility mappings are provided to preserve the API. The drivers can be corrected one by one and MFC'd without issue. o The size of pkthdr stays the same at 48/56bytes (32/64bit architectures).

| | | | | | | | | | | | | | | | | | | | | dereferencing, when checking for SO_REUSEPORT option (and SO_REUSEADDR for multicast), INP_REUSEPORT flag was introduced to cache the socket option. It was decided then that one flag would be enough to cache both SO_REUSEPORT and SO_REUSEADDR: when processing SO_REUSEADDR setsockopt(2), it was checked if it was called for a multicast address and INP_REUSEPORT was set accordingly. Unfortunately that approach does not work when setsockopt(2) is called before binding to a multicast address: the multicast check fails and INP_REUSEPORT is not set. Fix this by adding INP_REUSEADDR flag to unconditionally cache SO_REUSEADDR. PR: 179901 Submitted by: Michael Gmelin freebsd grem.de (initial version) Reviewed by: rwatson MFC after: 1 week
